Small‐cell lung carcinoma and acute onset of antiglial nuclear antibody‐positive limbic encephalitis

Abstract

Limbic encephalitis (LE) can present as a nonspecific manifestation preceding neoplastic disease. Having high clinical suspicion and using newer onconeural antibodies, like antiglial nuclear antibody (AGNA), can lead to an earlier diagnosis. We report a patient with AGNA‐positive LE who is later diagnosed and treated for small‐cell lung carcinoma.
